Is your website compatible with every device? Is your checkout process working from start to finish for every single smartphone or tablet on customers use to shop online? Are you sure you are not missing revenue due to a broken Proceed to Checkout page, and sending traffic to your competitor’s website instead? Are those errors causing fatal crashes, or do they just cause minor inconveniences?
The truth is, you don’t know.
Of course, you test your website regularly and all its most important features have been validated on the largest set of real devices you can afford. But you can’t cover the entire set of devices readily available to the public, and deadlines are always too short.
How, then, can you be sure that website errors don’t prevent your customers from completing their transactions?
